Abstract

PROBLEM TO BE SOLVED: To securely display the least content by preferentially receiving/ demodulating a broadcasting program stored as a priority reservation registration information among reservation registration information stored in a first means and storing the content in a second means. SOLUTION: At the time of a reservation reception mode, a controller 6 causes a tuner 2 to scan/select the channel of the program which is reserved/ registered, causes a code extraction part 5 to extract the content of the received program and takes it into a program memory 7a. It is assumed that a program A-a program are reserved/registered in a reservation memory 7b, and a program C, a program D and a program F are registered by setting priority modes, for example. At the regular reservation reception mode, all the registered programs are received irrespective of the priority flag of the reservation/ registration program and they are taken into the program memory 7a. Namely, the content is read from the memory 7a in the looking and listening of the user's reservation/registration program, and the video of the program can be outputted on a monitor.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a broadcast receiving apparatus suitable for implementation as, for example, a teletext receiving apparatus.

[0002]

2. Description of the Related Art As is known as teletext, a broadcasting system has been implemented in which text data to be an independent program is superimposed and transmitted in a video signal of television broadcasting. In this teletext, one program is composed of character data for several pages, and the teletext receiving device extracts the text data from the received video signal of the television broadcast to extract the text for each page. A video signal to be a broadcast screen is generated and supplied to a monitor device for display.

In this teletext, the page transmission interval of the program, that is, the interval at which the receiving device can receive the information of each page is about 20 seconds. Therefore, if a program consists of, for example, 10 pages, it takes about 200 to receive the program.
This will take seconds. Therefore, when viewing a teletext, if the user selects a program and then receives the information of the selected program and displays it on the monitor, the user will have to select the program from the actual display output. It means that you often have to wait.

For this reason, in the conventional teletext receivers,
A function called reservation registration is provided. In this case, when the user selects a program to watch in advance and makes a reservation registration, the receiving device stores the program content in the memory in response to the reception of the program. When the user selects the program for actual viewing, the content of the program is read from the memory so that it can be immediately displayed on the monitor.

For example, a case where the program is a weather forecast will be taken as an example. It is assumed that the content of this program is updated three times a day in the morning, noon, and evening, and that it is composed of about 10 pages. If the user reserves and registers this weather forecast program, the receiving device stores the program contents for 10 pages in the memory every time the weather forecast program that is repeatedly broadcast is received. As a result, even if the content is updated, the latest program content is always held in the memory as the weather forecast.

When the user selects a weather forecast program for viewing, the content of the program held in the memory is immediately displayed. For example, even if the user wants to see the contents of the fifth page, it can be displayed immediately by pulling it out from the memory. In this way, the reservation registration function eliminates the waiting time of the user when viewing the teletext, and can significantly improve the usability.

[0007]

By the way, such teletext programs include a program whose contents are frequently updated and a program whose contents are not so often updated. For example, the content that is broadcasted, such as a stock market or exchange information program, is 5
Some are updated every minute, while some are updated only a few times a year, such as railway timetable programs.

For this reason, if there are reservation registration programs whose contents are frequently updated in a plurality of TV channels, 1
It is preferable to shorten the reception time of one program as much as possible. Because the number of pages of the programs registered for reservation is large,
If it takes a long time to receive and store one program,
This is because when a user views a program whose content is updated in a short time such as stock market conditions, the content of the program held in the memory may not be updated to the latest one.

Therefore, as the program to be reserved and registered, one having a small number of pages and receiving and storing operations being completed in a short time is selected, and the update time of the entire program is shortened as much as possible to improve the updateability of the program. Although desirable, in reality, since the number of pages of a program varies depending on the information desired by the user, etc., if a program with a large number of pages is reserved and registered, the immediacy of the entire program is impaired.

The present invention has been made in view of the above circumstances, and an object of the present invention is to improve the immediacy of the contents of programs that users often watch.

[0011]

In order to solve the above problems, reception demodulation means for receiving and demodulating a broadcast, and reservation reservation information of a program can be stored in a state where normal reservation registration information and priority reservation registration information are distinguished. No. 1 storage means, reception control means capable of causing the reception demodulation means to receive a broadcast program according to reservation registration information, and second storage means capable of storing the content of the received broadcast program. When the reception control means is set to the priority mode, the reception demodulation means gives priority to the broadcast program stored as the priority reservation registration information among the reservation registration information stored in the first storage means. Then, the contents of the broadcast program are stored in the second storage means. Since the reception control means is set to the priority mode, the broadcast program stored as the priority reservation registration information is preferentially received and demodulated, and the program content is stored in the second storage means. It is possible to perform various reception processes.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION A teletext receiver as an embodiment of the present invention will be described below. FIG. 1 is a block diagram of a teletext receiver. The television broadcast radio wave received by the antenna 1 is selected by the television tuner 2, demodulated, and a video signal broadcast on that channel is output.

The video signal output from the television tuner 2 is supplied to the T terminal of the switch 3. The output of the switch 3 is supplied from the terminal 4 to the monitor device. Therefore, when the switch 3 is connected to the T terminal, the monitor apparatus is supplied with a video signal as a normal television broadcast, and the television broadcast is displayed.

There are various conceivable modes of connection between the teletext receiver and the monitor device (eg, television receiver). For example, the video signal may be connected in the RF signal form, or the composite video signal form, or Y / C. A video signal format, an RGB signal format, and the like are also conceivable. The configuration of the output circuit system in the preceding stage of the terminal 4 is different due to the difference in these signal forms, but this point will not be described in detail. It is also conceivable that the teletext receiver is built in a television receiver.

The code extracting unit 5 extracts data as a character broadcast superimposed on a predetermined line in the vertical blanking period in the received / demodulated video signal. The extracted data is once supplied to the controller 6. The controller 6 is composed of a microcomputer as a control unit. Then, the operation of each part is controlled by the control signal SG.

The controller 6 can supply the extracted teletext data as it is to the screen synthesizing section 8 to synthesize a video signal as a teletext program. Further, the controller 6 temporarily stores the extracted teletext data in the program memory 7
It is also possible to store it in a, read it out when the user views it, and supply it to the screen synthesizing unit 8 to synthesize a video signal as a teletext program. The output of the screen synthesis section 8 is supplied to the M terminal of the switch 3. When viewing the teletext, the controller 6 connects the switch 3 to the M terminal, whereby the monitor apparatus outputs the video as the teletext synthesized by the screen synthesis unit 8.

The operation unit 9 includes an operation key for the user to select a teletext program, a reservation mode key, and an operation key for a priority mode, which will be described later, which is a mode for giving the highest priority to reception of a program for which priority reservation registration has been made. Is provided. Regarding program selection, first, a channel operation key for selecting a channel of a broadcasting station is provided, and when the user selects a channel, the controller 6 controls the reception frequency of the television tuner 2 accordingly. Then, after selecting the channel, the user selects the program number. For selecting the program number, for example, "0" to "9"
The ten-key pad and the “#” key are provided. For example, if the user operates “1”, “2”, “3” and “#”, the program number “123 #” is designated.

Also, for example, after the user operates the reservation mode key, channel "1", program number "0", "0"
When the user operates "1" and "#" and further operates the reservation set key, the controller 6 determines that the program of the program number "001 #" of channel 1 has been registered for reservation (hereinafter referred to as "normal reservation registration"). The data "channel 1 / program number 001 #" is recognized and stored as reservation registration data in the reservation registration memory 7b.

Further, for example, after the user operates the reservation mode key, the channel "8" and the program number "1" are displayed.
When the user operates "0", "4", "#", and further, for example, presses the priority mode key and then operates the reservation set key, the controller 6 causes the program of the program number "104 #" of channel 8 to be reserved and registered in the priority mode ( Hereinafter, the data "channel 8 / program number 104 # / priority mode 1" is recognized as "priority reservation registration" and stored as reservation registration data in the reservation registration memory 7b. Clock section 10
Has a timer function that allows the user to set a predetermined time, for example.

The reservation registration memory 7b stores the reservation registration data thus set according to the user's operation. For example, as shown in FIG. 2, channels, program numbers and priority flags of various programs are stored as reservation registration data. Remembered.
For example, in the case of priority reservation registration data as described above, the priority flag is set to "1". The controller 6 normally, based on all the reservation registration data (normal reservation registration data and priority reservation registration data) registered in the reservation registration memory 7b, each time the reservation registered program is received, the code extraction unit 5
The program content extracted in step S7 is stored in the program memory 7a.

The storage capacity of the program memory 7a is set so that a relatively large amount of teletext contents, such as 300 pages, can be stored. For example, as shown in FIG. The program content is stored together with the channel number and the program number in accordance with. The amount of data as the content of the program depends on how many pages of the program the image is composed of, and has a different data size for each program.

By holding the program thus reserved and registered in the program memory 7a, the user wants to watch the program and designates the channel and program number of the teletext program as described above. When the operation is performed, the controller 6 can immediately read the program content from the program memory 7a and output the video of the program on the monitor device.

The operation relating to the reception mode realized in such a teletext receiver will be described below. First, in the normal reserved reception mode, the controller 6 causes the television tuner 2 to scan and select a channel of a program that is reserved and registered, and causes the code extraction unit 5 to extract the content of the received program. So that the operations that are taken into are continuously executed. For example, programs A to F are reserved and registered in the reservation registration memory 7b,
It is assumed that the priority mode is set and registered for the programs C, D, and F. In this case, in the normal reservation reception mode, as shown in FIG. 4A, regardless of the priority flag of the reservation registration program, all the registered programs are received and taken into the program memory 7a.

Note that (1) in FIG. 4 indicates that the priority reservation registration data has a priority flag set,
(0) indicates that it is ordinary reservation registration data for which the priority flag is not set.

The processing of the controller 6 for such a television tuner 2 is shown in FIG. That is,
When the TV tuner 2 is set to the channel of the program reserved and registered in step F101 and the predetermined program broadcast reserved and registered in step F102 is received, the content of the program is taken into the program memory 7a. And step
It is determined whether the program received in F103 is completed, that is, whether all pages of the program have been captured, and if not completed, the process returns to step F102 to maintain program reception,
Program data is continuously taken into the program memory 7a. On the other hand, when it is determined in step F103 that the program broadcasting is completed, the television tuner 2 is set to the channel of the program which has not been received in step F101 according to the reservation registration data stored in the reservation registration memory 7b. It will be.

By repeating such processing, when the user views the program registered for reservation, the program content is immediately read from the program memory 7a, and the video of the program can be output on the monitor device. However, in general, the programs that are reserved and registered and stored in the program memory 7a include
The contents are frequently updated, the ones that are not updated frequently, the ones with many pages, the ones with few pages, and so on.Therefore, when users watch a program whose contents are updated frequently, The program content read from the program memory 7a and displayed may not be the latest.

Therefore, in this embodiment, a priority reservation registration function is provided so that the user can receive only the priority reservation registration program registered by depressing the priority mode operation key provided in the operation unit 9 described above, for example. The program contents of the program memory 7a are updated. In other words, the user makes priority reservation registration of programs that are frequently viewed, such as stock market programs, whose contents are frequently updated, and makes regular reservation registration of programs that are not so updated, such as station timetables, and makes priority reservation registered programs. Shortly before viewing, for example, the priority mode operation key provided on the operation unit 9 is pressed.

When this priority mode operation key is pressed,
For example, as shown in FIG. 4B, the controller 6 cancels the receiving operation and reserves the registration with respect to the television tuner 2 even if the program B received at that time is incomplete. The program C in which the priority mode is set among the programs is discriminated, and the TV tuner 2 is caused to scan and select the channel. Then, the content of the received program is extracted by the code extracting section 5 and loaded into the program memory 7a. Then, after the reception operation of the program for which the priority mode is set is completed, the normal reservation reception mode is switched and the reception operation of the program stored in the reservation registration memory 7b is executed.

The processing of the controller 6 for the television tuner 2 in such a priority reservation reception mode is shown in FIG. That is, when the priority mode operation key is pressed, the TV tuner 2 is set to the channel of the program for which the priority reservation is registered in step F111, the predetermined program broadcast for which the priority reservation is registered is received in step F112, and the content of the program is received. Will be taken into the program memory 7a. Then, in step F113, it is determined whether or not the received program is completed, and until the program is completed, the reception of the program for which priority reservation registration is performed and the loading into the program memory 7a are maintained as the process of step F112.

When the program broadcast taken in in step F113 is completed, other priority reserved programs not yet received among the priority reservation registered data programs stored in the reservation registration memory 7b in step F114. If there is a program that has not been received, and there is a program that has not been received, the TV tuner 2 is set to the channel of the program for which the next priority reservation is registered in step F111, and the receiving / storing operation is executed. . This receiving / storing operation is performed until all the programs registered in the reservation registration memory 7b as the priority reserved programs are received. Then, step F114
If it is determined that there is no prioritized reserved program that has not been received in step 1, that is, if it is determined that all prioritized reserved programs have been received and the program content held in the program memory 7a has been updated, the normal reception mode Return to Reservation registration memory 7
The program registered in a will be received (F11
Five). That is, the processing shifts to the processing in FIG.

Therefore, for example, the user is frequently updated as a program for priority reservation registration, and in particular, the program of character data broadcasting that the user wants as the latest information is registered and provided in the operation unit 9 when waking up in the morning, for example. By performing the priority mode operation that is performed, for example, after breakfast, the data content of the program that has been registered for priority reservation is updated to the latest one,
The video of the program can be immediately output from the program memory 7a and output to the monitor device.

When the user always watches a teletext program for which priority reservation registration is performed at a fixed time, the user does not have to perform the priority mode operation each time, for example, the clock section 1
It is also possible to automatically update the content of the program for which priority reservation registration has been performed by the timer function provided in 0 at a set predetermined time.

In this embodiment, the program memory 7a and the reservation registration memory 7b are provided. However, the present invention is not limited to this, and the reservation registration memory and the program memory may be formed as an integral memory element. Alternatively, the internal memory of the controller 6 may be used.

[0034]

As described above, in the broadcast receiving apparatus of the present invention, among the reservation registration information stored in the first storage means,
At least the user always wants the latest program content by preferentially receiving and demodulating the broadcast program stored as the priority reservation registration information by the receiving and demodulating means and storing the content of the broadcast program in the second storage means. The latest program can be surely presented.
